Thames Valley Police's forensic investigation unit is at the store, which remains closed.

A spokesperson for Hammerson, which owns The Oracle, said: "It is with great sadness that we learned a child had passed away in hospital on Monday evening as a result of injuries sustained in an incident at Topshop in the centre.

"Our thoughts are with the family at this tragic time. We are assisting the police, local authority and the retailer with their investigations into the incident."
